Sarah Lancashire and Reece Shearsmith will star in Betty Blue Eyes, a new musical based on the film "A Private Function," that producer Cameron Mackintosh is bringing to the West End's Novello Theatre, beginning performances March 19, 2011.

Just as Prince William has announced his engagement to Kate Middleton and a royal wedding is planned for next year, the show also revolves around the earlier royal wedding of Princess Elizabeth and Prince Philip. The topicality is enhanced by the setting. According to press materials, belts are being tightened and the country's long-suffering citizens are being told by the government that there will be fair shares for all in return for surviving Austerity Britain. Meanwhile local officials feather their own nests by taking far more than their own fair share. It is of course 1947 and having won the war Britain seems to have lost the peace and the country is staggering under the burden of acute rationing, unemployment, and the coldest winter for decades. The only bright spark on the horizon is the impending Royal Wedding of Princess Elizabeth and Prince Philip.

"A Private Function," scripted by Alan Bennett, centered around Betty, an adorable pig, who is being illegally reared to ensure the local dignitaries can celebrate the Royal Wedding with a lavish banquet while the local population make do with spam. Ron Cowen and Daniel Lipman have now adapted and expanded this story for the stage, and George Stiles and Anthony Drewe (currently represented on Broadway by their additional songs for Mary Poppins) have written the score.

In a press statement, Mackintosh commented, "Even though my recent productions of Oliver!, My Fair Lady, Mary Poppins and the new Les Mis have all had great success, Betty Blue Eyes is my first original musical in over 10 years. As a long time admirer of Alan Bennett's wickedly funny screenplay for the film 'A Private Function,' I immediately fell in love with this infectious and delicious musical treatment which has expanded on the original . It is an utterly British and suitably crackers musical and yet surprisingly was the idea of two American writers Ron Cowen and Daniel Lipman – but you’d never know it! As we all face Austerity Britain and a Royal Wedding, Betty Blue Eyes proves that British pluck will make sure good times are just around the corner."
